最近看到一个PHP的很有意思的库React，官网上的说明：Event-driven, non-blocking I/O with PHP. 我就想问下，有人用过这个东西吗？它和Node.js的区别在哪里？
回复内容：
没差别。都是做异步io，单线程单进程reactor模型。一个PHP，一个js。个人觉得后台程序还是同步io的使用场景更多些。99%的场景用同步阻塞多线程/多进程就够了，1%的场景才用得到异步io，node.js主要是为web前端程序员打开了后端大门。而且前端程序员用ajax习惯了，天生就熟悉异步回调。所以仅仅和react.PHP比没有可比性。
npm生态圈更繁荣，react这个估计没太多人用。
在超大型项目上node目前应用也不太多的，react就基本没有了。还是看看swoole吧，同步io和异步io都支持。百度地图、百度直达号、腾讯企业QQ、QQ公众号、战旗直播等大项目都在用。小项目就更多了，贴不过来。 谢邀，不过矮木骚瑞，这个我没有接触过，不能乱说，帮你邀请了几个人，看能不能得到答案~ 区别在于JavaScript可以做到全栈语言的统一（FE，BE，DB），享有更好的生态环境（NPM），语言本身的设计也更为灵活（多范式）。
What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AMReasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.
How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AMMethods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.
What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AMMultiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AMConfiguring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AMThe main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.
How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AMImplementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.
What is a session ID?Apr 24, 2025 am 12:13 AMSessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.
How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AMManaging sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
